All the fun of the fair - we check out dodgem car physics. See you later - we say goodbye to another caravan! Do fast music - and distracting passengers - make you drive badly? We get fruity down at the lab. Bone idle, bog cleaning with the Lazy Man's Guide. Meals in minutes - more microwave mayhem. Can a monkey psyche out a psychic? Elbow licking - the sequel. Plus the return of Tall v Small!
